Embodiment of the invention provide a reverse name lookup function for providing an absolute path name or file name and absolute path name to the file name parent directory based on a vnode reference, NFS file handle reference, or file identifier reference associated with a computer virtual file system. A control module chooses the at least one separate video layer stream based on the device parameter. A length of inter-burst periods of the mobile radar transceiver having an inter-burst timing can be determined. A thermal print head will heat a composition on the thermal transfer ribbon in order to transfer it to the receiver substrate. Sealing portions 26a are formed on one of the electrode substrate 10 and the cavity substrate 20, each of the sealing portions 26a has a plurality of sealing layers laminated one another, and each of the sealing layers is made of a sealing material 25 for isolating a space formed between the individual electrode 12 and the diaphragm 22.
